Abstract The reliable use of ultrasonic metal welding requires a thorough understanding the relevant bonding mechanisms. This article presents an approach to systematically investigate relation between mechanical properties and interface selected Al/Cu Al/GFRP joints. hypothesis is that microstructure tensile shear strength specimen can be related their presented by contact stiffness damage ini...

The interface shear strength of polypropylene pipeline coatings and marine sandy soils was investigated through direct surface-over-soil box testing. Polypropylene specimens were acquired by removal from existing manufactured steel pipes test fabricated to closely resemble typical compositions particle size distributions North Sea sediments. sands varied according their coarse fractions, with 0...
